ISLAMABAD - Pakistan on Saturday slammed a senior US official's statement on the country's missile capabilities and delivery means, calling it "unfortunate."

"The allegations are unfounded, devoid of rationality and sense of history. The recent spate of US allegations towards a major non-NATO ally would be unhelpful for the overall relationship, especially in the absence of any evidence in this regard," said Mumtaz Zahra Baloch, spokesperson of Pakistan's Foreign Ministry.

Baloch said that Pakistan's strategic capabilities are meant to defend its sovereignty and preserve peace and stability in South Asia, and any irrational assumption of hostile intent from Pakistan by any other country, including the United States, is perplexing as well as illogical.

Pakistan has always sought to engage constructively with the United States on all issues, including the need to pursue a balanced approach to security and stability in the region, she said.
